factors affecting the license plate recognition rate when the license plate recognition system < / a > is applied

I. installation technology of license plate recognition system The professionalism and standardization of the installation technology of the license plate recognition system will affect the license plate recognition rate of the practical application of the license plate recognition system. For example, when installing the camera unit of the license plate recognition system, if the camera angle is not adjusted properly, the camera will not be able to capture and collect accurately, and the actual application of the natural license plate recognition system will greatly reduce the license plate recognition rate

II. Recognition algorithm technology of license plate recognition system

License plate recognition algorithm is the core technology of license plate recognition system. At present, the recognition algorithms used by license plate recognition system on the market include buried coil detection, infrared detection, radar detection, video detection and so on. These methods have their own advantages and disadvantages. The license plate is complex and diverse in color composition, font composition and number composition. At this time, if the algorithm of the license plate recognition system does not meet the requirements of accurate operation and recognition in some technologies, it will also directly affect the recognition rate of the license plate recognition system

III. actual shooting quality of camera unit of license plate recognition system

The actual shooting quality of the camera unit of the license plate recognition system will also directly affect the recognition rate of the license plate recognition system. When the camera unit of the license plate recognition system is in actual shooting, if the brightness or clarity of the shooting environment is not enough, the fill light of the camera is not enough, and the speed of the vehicle is too fast, it will directly affect the actual application of the license plate recognition system and the license plate recognition rate

IV. the quality of license plate will also affect the actual recognition rate of license plate recognition system

Limited by the recognition technology of the current license plate recognition system, the quality of the license plate will also directly affect the actual application of the license plate recognition system and the recognition rate. The fuzzy display of numbers or words on the license plate, the rust and pollution on the surface of the license plate, the fading of the font of the license plate, the falling off of the surface paint, the inclination, reflection and occlusion of the license plate, or the false license plate and multiple license plates will affect the recognition effect of the license plate recognition system and reduce the actual application recognition rate of the license plate recognition system
